Description
The MCRJ232768F12200H3H is a specialized, compact quartz crystal resonator designed for low-power, high-precision timing. With a nominal frequency of 32.768 kHz, it serves as the industry-standard timebase for Real-Time Clock (RTC) circuits in everything from digital watches and consumer electronics to industrial instrumentation and IoT devices.
Packaged in a space-efficient 6.2mm x 2.1mm diameter cylindrical radial housing, this crystal is ideal for through-hole PCB assembly where vertical space or footprint minimization is required. It is engineered for long-term reliability and stable performance within a thermal range of -20°C to +70°C. Featuring a tight frequency tolerance of ±20 ppm and a standard load capacitance of 12.5 pF, it ensures your system maintains precise timekeeping even in battery-constrained environments.
